T0 all whom it may concern:

Be it known that I, THOMAS J. GREENWOOD, of Warren, in the county of J 0 Daviess and State of Illinois, have invented a new and 1111- proved Crimping-Machine, of whieh the following is a speeifieation:

'Ihe object of my invention is to provide asimple and efleient machine for erimping and pasting tongue-boots at the same time, whereby a eonsiderable eeonomy of time andlabor aan he effeeted, besides some waste of material avoided.

The invention consists of a board or baseplate, whereon is a crimping bloek or 0rmer, on which the boot is to be stretehed; a elannp, which is the counterpart of some portions of the bloek, and the base-plate for pressingthe leather int0 shape upon it; and a shaft, aam, and lever, for actuating the elamp, the shaft being detaehably supported in its bearings, so that it aan he taken out of the way readily 'or removing and applying the clamp, and the elamp being notehed or serrated in the seat 0n whieh the earn works, t0 hold it whenever it comes te rest.

. Figure 1 is a plan view; and Fig. 2 is a sectional elevation of Fig. 1, taken on line x .0

A is the base-plate; B, the crimping-bloek; C, the clampng plate; E, the shaft; F, the aam; G, the lever, and H the bearings of the shaft. The back or top of the elampingplate is serrated. at I, to cateh the point of the eam whenever it e0mes t0 rest in pressing down the leather, and one of the bearings, H, has an inelined slet, J, to allow of taking out and putting in the shaft readily for affording the requisite 'reedom in putting en and. taking off the clamping-plate. K represents the tongue front, and L the leg part, which I first cut out in just the size and shape I want them, and lay the leg part on the base-plate, and partly en the erimping-bloek', as shown. the part of the tongue front whieh is to overlap the leg part, and plaee it on the erimp with the pasted edge overlapping the leg part, as shown at M. Then I apply the clamp-plate 0 and eam,ancl press them down to the shape of the THOMAS JEFFERSON GREENWOOD.
